CARRIAG E-TOP JOINT.

SPECIFICATION forming part of Letters Patent No. 430,638, dated June 24, 1890.

- Application filed February 15, 1890. Serial No.340,550. (No model.) Patented in Canada January 9. 1890. No. 33,361.

To (LZZ whom it may concern:

Be it known thatl, GEORGE GILLIES, a subject of the Queen of Great Britain, residing at Gananoque, in the Province of Ontario, Canada, have invented a new and useful-Joint for Carriage-Tops, 850., (patented in Oanada,No. 33,361, dated January 9, 1890,) of which the following is a specification.

This invention relates to certain improvements in joints for carriage-tops, props, seatrails, bow-sockets, and the like; and it has for its object to construct a joint of this class which shall be simple, easily applied, and in which the parts joined shall not easily become loosened by wear, while in the event of their becoming so loosened the joints may be readily tightened and restored to a perfect condition.

With these ends in View, the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure l is a side elevation of a carriage-top equipped with my improved joints. Fig. 2 is a perspective view of one of the seat-rails detached. Fig. 3 is a sectional view of the seat-rail, pintle, and bow-iron, taken on the line a; no in Fig. 1. Fig. 4 is a sectional view of one of the bows, the bowplate, pintle, top-prop, and extension-brace, taken on the line y y in Fig. 1. Fig. 5 is a perspective detail View of the bowplate and pintle for the front bow separated from each other. Fig. 6 is a perspective detail view of the bow-plate and pintle for the middle bow separated from each other.

Like numerals of reference indicate like parts in all the figures.

1 designates the bow-iron, and 2 is the seatrail, which are connected by means of a pintle 3, the ends of which are provided with right and left hand screw-threads, as shown at 4. The threaded ends of the pintle screw into correspondingly-threaded recesses 5 in the bow-iron and seat-rail, which, by turning the pintle axially,will thus be connected. The body of the pintle 3 is preferably polygonal in shape, so as to be readily engaged and rotated by means of an ordinary wrench. It will be seen that when the parts are thus c011- nected one of the members constituting the joint-namely, the bow-iron 1will be capable of rocking on the pintle, so as to allow the top to be raised and lowered.

6 designates an arm extending from the seat-rail and forming a support for the top brace 7. The outer end of the said arm 6 is screw-threaded, as shown at 8, to engage the screw-threaded recess or perforation at the lower end of the top brace 7, which latter is screwed onto the said arm 6 prior to having its upper end connected to the prop on the bow. The ends of the top braces and the eyes of the bow-sockets and seat-rail are thickenedor enlarged to form caps or circular terminations 9, and the eyes or caps thus formed are bored and interiorly screwthreaded for the purpose of receiving the screw-threaded ends of the connecting-pintles.

The bows, which are designated by 10, are connected in the usual manner at their lower ends with the bow-iron 1. The front bow is connected to the middle bow by means of a jointed brace 11, the front end of which is connected to the front bow by means of apintle 12, one end of which is screw-threaded to engage a screw-threaded recess at the front end of the brace 11. The opposite end of the pintle 12 has a female-threaded recess to receive a screw-threaded pin 13, which extends laterally from a plate 14, that is bolted or otherwise suitably secured to the said front bow. The pintle 12 is provided with an annular flange 15, having a series of recesses or notches 16, and the plate 14 is provided with a screw-threaded recess 17 to receive, the point of a pin or bolt 18, which is fitted in one of the notches of the flange 15 of the pintle. The latter having been properly adjusted may in this manner be prevented from unscrewing and coming loose. At the same time by removing the pin 18 it may be readily tightened whenever desired. The upper end of the middle bow 10 has secured to it a plate 19, which is in all respects similar to the plate 14, and is provided,like the latter, with a laterally-extending screw-threaded pin 20.

21 designates the pintle, which has a femalethreaded recess 22 to receive the pin 20, and is provided at its opposite end with a screwthreaded pin 23, upon which the rear end of the jointed brace 11 is adjusted loosely, after which the pintle is turned to cause the end of the screw-threaded pin 23 to engage a female-threaded recess 24 in the upper end of the jointed top brace 7. The pintle 21 is provided, like the pintle 12, with a notched flange 25, to be engaged by a pin 26, adapted to be adjusted in a screw-threaded recess 27 1n the plate 19, thereby serving to hold the pintle from rotating.

The operation and advantages of my invention will be readily understood from the foregoing description, taken in connection with the drawings.

The parts of the device may be very easily and quickly put together or separated, as oocasion may require, and the several parts will rock freely upon the pintles by which they are connected. l/Vhenever the parts become loose from wear they may be quickly and easily tightened and restored to a perfect condition.

Having thus described my invention, what- I claim is- 1. In a carriage-top, the combination, with the bows, of the plates having laterally-extending screw-threaded pins, the pintles provided at their inner en ds with fem ale-threaded recesses and at their outer ends with screwthreaded pins, and the jointed brace having its ends mounted upon the said pins, substantially as set forth.

2. The combination of the bows, the plates having laterally extending screw threaded pins, the pintles having female-threaded recesses at their inner ends and screw-threaded pins at their outer ends, and provided with notched flanges, and the holding-pins adapted to enter recesses or perforations in the bowplates and to be fitted in the notches of the flanges, substantially as set forth.

3. The combination of the seat-rail, having the arm screw-threaded at its outer end, the bow, a plate secured to the latter and having a laterally-extending screw-threaded pin, the jointed top-brace having its lower end screwed to the arm extending from the seat-rail, and the connecting pintle provided at one end with a female-threaded recess and at the other end with a screw-threaded pin, substantially as set forth.

4. As an improvementin carriage-tops, the combination of the seat-rail having a laterally-extending arm screw-threaded at its outer end,thebow-iron,arightandlefthandthreaded pintle connecting the seat-rail and bow-iron, the hows, the plates mounted upon the front and middle bows and havinglaterally-extending screw-threaded pins, the jointed rails, the pintles having female-threaded recesses at their inner ends, screw-threaded pins at their outer ends, and notched flanges, said pintles connecting the bow-plates with the ends of the jointed brace, and the top-prop having its lower end screwed onto the laterally-extending arm of the seat-rail and its upper end connected with the screw-threaded pin of the pintle of the middle bow adjacent to the rear end of the jointed brace, which is mounted.

loosely upon said pintle, substantially as set forth.

In testimony that I' claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
